Definitions

  • the invention relates to a double-walled tube formed of an envelope external metal and a flexible and protective internal envelope, intended for store and distribute detergents, hygiene products or particularly aggressive cosmetic products with regard to the envelope external metallic, such as hair dyes.
  • Metal tubes are appreciated for their high restitution rates.
  • the perfect plasticity of the metal prevents any return of the towards the inside of the tube when the user has finished pressing on the skirt of the tube.
  • the metal envelope is very sensitive to corrosion from when it comes to containing particularly acidic or alkaline products.
  • Patent application FR-A-2 322 058 presents a double-walled tube made up of two tubes produced separately and joined by their necks.
  • the metal tube constitutes an external envelope which is protected from the aggressive product by a internal plastic tube.
  • the top end of the neck of the tube internal plastic largely exceeds the top end of the neck of the tube external metal.
  • the protruding part is flared in the shape of a trumpet opening above the metal neck, then embedded in one end plastic overmolded above and around the metal neck.
  • the realization of such a tube therefore requires at least three separate operations: threading the inner tube in the outer tube, the flaring of the projecting end of the neck of the inner tube and then the delicate overmolding of a material crown plastic on the edge of the metallic external neck.
  • Patent application JP-A-7277349 describes a double-walled tube made up also of two tubes produced separately but linked together at the level of their necks by means of a mouthpiece which is forcibly threaded around all.
  • the preamble of claim 1 is based on this state of the art.
  • FR-A-2 322 058 the top end of the neck of the tube internal largely exceeds the top end of the neck of the metal tube external.
  • the protruding part is flared then folded outwards in covering the external metal neck.
  • the end cap is pushed in and rests on the outside of the folded part of the inner tube.
  • JP-A-7277349 recommends that the internal tube, which is in plastic material, has at least at its ends a smooth wall, free of mold seal line. Such a smooth wall is obtained by molding by injection the inner tube.
  • the end of the neck of the inner plastic tube should be fairly thin, which gives it a poor buckling resistance and does not facilitate the first step of setting form which consists in flaring the end of this neck.
  • This step necessary, is complicated by the need to design a tool that maintains this neck perfectly during the flare.
  • the tubes large capacity, having a skirt length greater than 130 injection molding does not allow for easy thin neck of plastic material resistant to cracking under constraint. Indeed, these tubes require the use of materials capable of injection over a great length into a narrow air gap. Such materials must have a high melt index, greater than 15, and are much more sensitive to stress cracking in contact with the contained product that usually used materials, with a lower melt index (0.2 to 2).
  • the internal plastic envelope by other more economical means, for example blow molding or molding of a head on an extruded or laminated welded skirt. It would take this will get rid of the obligation to have an exterior wall free of defects geometric, such as a mold joint line, or even get rid of the need to have a reproducible neck geometry, these conditions being necessary in JP-A-7277349 to obtain a perfect seal of the connection between the bottlenecks.
  • the Applicant therefore sought to economically produce a tube to double wall with a flexible and protective inner shell and a external metallic envelope, intended to store and distribute products aggressive towards the metal envelope, the two envelopes being linked between them by their ends, the connection at the level of the necks having a improved tightness, especially for very long tubes.
  • the object of the invention is a double wall tube intended to store and distribute products aggressive, with a inner tube having a skirt, a shoulder and a neck internal delimiting an internal orifice, and an external tube metallic having a skirt, a shoulder and a neck external, the two tubes being connected together at their necks by an end piece comprising a bottom and at least one external skirt characterized in that the end piece is also provided with an internal skirt so that, when the endpiece is forced in, the internal and external necks are buried between said internal and external skirt, the external wall of said internal skirt having a generally frustoconical profile and imposing an expansion circumferential to the middle parts of the necks and a flare of the ends of said necks.
  • the part of the internal skirt of the nozzle which is introduced into the internal neck has, over a length at least equal to 2 millimeters, a outer diameter greater than the initial diameter of the internal orifice.
  • the internal tube can be made of any flexible material capable of protecting the metallic outer shell of the corrosive packaged product.
  • an internal plastic tube It is obtained by any means known: injection molding, blow molding, head molding then welding thereof on a welded extruded or laminated skirt.
  • His neck is devoid of intaglio or raised details but may include seal lines of mold. It is thick enough to avoid any risk of buckling at during the insertion of the nozzle on the necks.
  • the geometry of this neck cylindrical hollow should preferably check a height to thickness ratio less than 10, so as to avoid an "accordion" deformation of said neck.
  • the outer tube is metallic. It has a skirt, a shoulder and a neck. Before the tip is inserted, the internal tube is threaded into the external tube.
  • the outside diameter of the internal neck being substantially equal or very slightly smaller than the inside diameter of the external neck, the two necks are find very close to each other on a certain common height by their outer and inner walls respectively.
  • the internal bottleneck does not or very little beyond the external neck: it is not essential to fold it back over the end of the external neck.
  • the tip has an external appearance similar to the tips of the prior art, it can have an external skirt fitted on its external wall with means of secured with a plug, for example a thread. It is maintained firmly straddling the external neck thanks to fixing means such as latching beads located respectively on the wall external of the external neck and on the internal wall of the external skirt of the mouthpiece.
  • fixing means such as latching beads located respectively on the wall external of the external neck and on the internal wall of the external skirt of the mouthpiece.
  • anti-rotation means also in the form of longitudinal fins with sections complementary for example, located on the outer wall of the external neck.
  • the endpiece is precentred, the precentring being facilitated by the presence of the internal skirt, and the fins are tapered in their upper ends with respect to the fins of the external neck and in their lower ends with respect to the fins of the outer skirt of the mouthpiece.
  • the bottom of the end piece is at a distance from the latching bead, located on the inner wall of the outer skirt of the end piece, such that, at the end of insertion the end cap, the inner wall of this bottom does not crush the ends flared from the bottlenecks.
  • the bottom of the end piece does not bear on any slices of bottlenecks.
  • the inner skirt of the end cap was forced into the hole internal, the external diameter of the orthogonal sections of said internal skirt being, on a part in contact with the internal neck and of length at least equal to 2 millimeters, greater than the initial diameter of the internal orifice, i.e. the diameter of the internal orifice before the tip is inserted.
  • This minimum length must be respected whatever the outside diameter of the neck envisaged, practically understood between 4 and 25 millimeters.
  • the profile of the external wall of the internal skirt is generally frustoconical, the open end of the skirt being oriented towards the apex of the cone, so that, during its forced insertion inside the internal orifice, the internal skirt imposes plastic deformation, resulting in a flare, the ends of the two necks.
  • the internal skirt of the nozzle therefore plays a double role: it is first, during the insertion by force of the nozzle, a tool which imposes a circumferential expansion on the middle parts of the necks, the internal neck, in direct contact with the skirt, being more stressed, and which then requires flaring of the ends of the necks. It is finally a effective sealing skirt throughout the use of the tube.
  • the internal neck in direct contact with the internal skirt of the nozzle, undergoes a circumferential expansion deformation and its outer wall is flattened against the inner wall of the external neck by transmitting radial forces oriented towards the outside, which ensures contact between these two walls all the more intimate as the external neck is less likely to deform, that is to say more rigid and harder, than the internal neck.
  • the internal skirt of the end piece is preferably thicker near its fasteners.
  • a preferred embodiment of the invention consists in giving the internal skirt of the endpiece a cylindrical inner wall and an axisymmetric outer wall, of shape cylindro-bitronconic, the middle part being cylindrical, the other two truncated.
  • the end of the metallic external neck is deformed so that it comes to bear on the inner wall of the mouthpiece.
  • the contact between the two deformed neck ends is thus maintained between the bottom of the internal skirt and that of the external skirt of the mouthpiece.
  • the bottom of the latter is thick and its wall inside is smooth, with a diameter substantially equal to the outside diameter of the external neck increased by a value less than the difference between the diameter of the cylindrical part of the internal skirt of the nozzle and the initial diameter of the internal orifice.
  • the internal neck is quite thick, which reduces the influence of a possible local excess thickness of the external wall of the internal neck on the quality of tightening and sealing.
  • the tip according to the invention has the advantage of locating the tight contact on the first diameter encountered by the product. There's no risk of product retention in more or less peripheral areas stressed during the use of the tube. On the other hand, intimate contact is located on the smallest diameter, which allows a more intense tightening and more efficient for a given diameter difference.
  • the tip is made of a harder and more rigid material than the material of the inner tube, which is also less hard and less rigid than that of the outer tube.
  • PP polypropylene
  • PE.BD low density polyethylene
  • the inner skirt of the nozzle must be thin enough to leave an opening suitable for product delivery rate and thick enough to impose the deformations sought at the two necks, while resisting mechanically to the forces which were generated during the sinking by dint of the tip and which persist, while relaxing, throughout the use of the tube.
  • the skirt is preferably in continuity of material with the end piece, for example molded in rigid plastic material, such as polypropylene.
  • the outer aluminum tube is fully annealed after shaping, which gives it flexibility in its thin areas.
  • the inner tube is made of the most flexible and as hard as possible material, resistant to stress cracking in the presence of an aggressive medium such as than a hair dye. It is preferably made of a plastic material such than low density polyethylene.
  • the applicant has tested different geometries in varying in particular the diameters and thicknesses of necks and skirts from the mouthpiece.
  • the best sealing conditions were obtained with a internal neck approximately as thick as the cylindrical part of the internal end cap skirt.
  • the external neck may be thinner than the two others, the metal being much more rigid.
  • it can be further thinned to typically half the thickness of the neck internal so that it flares plastically without great resistance, which facilitates the flaring of the internal neck, the latter remaining thicker than in the middle part.
  • the internal neck is thus "pinched" in its middle part between a flared end that is not or little thinned and a non-deformed base, its trapping helping to firmly maintain the inner tube inside the outer tube.
  • the deformation imposed by the internal skirt of the nozzle corresponds to a tightening of 3 to 8%, preferably 4% to 6%, that is to say that the outside diameter of the cylindrical part of the internal skirt of the nozzle is greater, by approximately 5%, than the initial diameter of the internal orifice.
  • a weaker tightening does not give satisfactory sealing conditions all throughout the life of the tube. Indeed, a certain loosening, more or weaker after initial tightening is observed after a few weeks at Room temperature.
  • a greater tightening results, during the insertion of the end piece on the necks, or an accordion deformation of the neck of the inner tube, or, if the thickness of the inner neck is large, a insufficient penetration making assembly impossible.
  • a second object of the invention relates to the nozzle itself comprising a bottom and an external skirt provided with latching and anti-rotation means, characterized in that it includes, also attached to its bottom, a skirt internal whose profile of the external wall is generally frustoconical, the open end of the skirt being oriented towards the apex of the cone.
  • this internal skirt is thicker near its fastener on the bottom of the mouthpiece. It advantageously has a cylindrical inner wall and a wall external cylindro-bitronconic, the frustoconical and cylindrical parts having approximately the same height, the frustoconical parts making a half-angle at the summit between 5 and 20 °.
  • This nozzle is preferably in one hard plastic material, such as polypropylene.
  • Figure 1 shows the axial section of a double-walled tube head according to the invention surmounted by the end fitting before being forced into it internal and external bottlenecks.
  • FIG. 2 represents the double-walled tube head according to the invention after forced insertion of the nozzle on the necks.
  • the left side is a axial half-section through a diametral plane passing a longitudinal fin of the nozzle
  • the right part is an axial half-section through a diametrical plane passing through a longitudinal fin of the external neck.
  • the double-walled tube 1 comprises an internal tube 10 and an external tube 20 made of annealed aluminum.
  • the internal tube 10 is obtained by overmolding a head 12 in PE.BD (low density polyethylene) on a skirt 13, also in polyethylene, with a diameter of 24.3 mm and a thickness of 250 microns.
  • PE.BD low density polyethylene
  • the internal neck 11 defines an internal orifice 14. Its top end is the edge 18.
  • the external annealed aluminum tube 20 has a skirt 25 with an external diameter of 25 mm and a thickness of 120 microns. It has a shoulder 24 and a neck 21 , the top end of which is the edge 28.
  • the external diameter of the internal neck 11 and the internal diameter of the external neck 21 are equal to 8.7 mm.
  • the internal neck 11 has a thickness of 0.75 millimeters.
  • the external neck 21, 0.5 mm thick, is provided, on its external wall, with a snap rim 23 situated at the base of the neck and longitudinal fins 22 which extend along said wall outside up to 1 mm from the end.
  • the inner tube 10 is introduced into the outer aluminum tube by conventional means: a mandrel threads inside the inner tube and drives it inside the outer tube whose shoulder and head are immobilized by a tool which follows its external shape. At the end of threading, the edge 18 of the internal neck 11 exceeds the edge 28 of the external neck 21 by a few tenths of a millimeter.
  • the external neck and the internal neck have a common contact height H of approximately 4.7 mm.
  • the end piece 30 has an internal skirt 31, a bottom 34 and an external skirt 35 provided on its inner wall with fins 42 which are intended, in combination with the fins 22 of the external neck 20, to immobilize the end piece 30 in rotation. and, on its outer wall, with a thread 41, for the screwing of a capsule intended to plug the dispensing orifice 40.
  • the cylindrical part 32 of the internal skirt 31 has a diameter of 7.5 mm, which imposes a tightening of 0.3 mm when the end piece 30 is pressed onto the necks 11 and 21. The effect of a certain creep is felt after a few days, causing permanent deformation of the two necks and a reduction in the Tightening. The latter nevertheless remains greater than 0.1 mm.
  • the external skirt 35 of the end piece 30 has on the side of its attachment a thick part 36, the smooth internal wall of which has a diameter of 9.8 mm does not abut against the anti-rotation fins 22 of the external neck .
  • the fins 42 are introduced into the intervals left by the fins 22 of the external neck 21, the cylindrical part 32 of the internal skirt 31 of the end piece 30 forces the necks to expand 0.3 mm then the frusto-conical part 33 close to the attachment to the bottom 34 of the nozzle 30 imposes a flaring at all of the ends of the necks 11 and 21.
  • the external neck 21, with an external diameter of 9.7 mm flares by 0.1 mm and then comes to rest on this smooth part of the inner wall of the outer skirt 35 of the end piece 30.
  • the outer skirt 35 of the end piece 30 is also provided towards its open end with a latching bead 37.
  • the position of this latching bead 37 relative to the bottom 34 of the end piece 30 is chosen so that 'at the end of the snap-fastening, there is no support of the internal face 38 of the bottom 34 of the end piece 30 on the flared top ends of the necks 11 and 21. This position is also such that the start of the flaring occurs before the start of the latching, which reduces the efforts required to drive the endpiece.
  • Fifty double-walled tubes produced using this method of the invention have undergone this test, which consists in injecting air inside the tubes until an overpressure of 500 g / cm2 is obtained. These tubes are then plugged then immersed in water for 30 seconds. No leaks were detected.
